The city's oldest neighborhood preserves the enchantment of cobble stone streets, low houses with barred windows and lanterns that light up in the evening. Ten blocks from the Plaza de Mayo, at Humberto Primo and Defensa streets, is Dorrego Place, the neighborhood's neuralgic tourism center. Indeed, the flea market there with its old records, glasses, porcelain, silver spoons and clothes, attracts multitudes.

The area's antique stores, the tango street performers and the restaurants and bars located around the square on neighboring streets add much to the zone's attractiveness. San Telmo is also synonymous to tango. There are bars and establishments that offer shows where you can also practice a few steps to the sound of the Bandoneon. It is worth taking a stroll through the Pasaje Giuffra and Lezama Park, a large green area covered with old vegetation. In the vicinity there are small antique bars with wooden furniture and restaurants that specialize in grilled meat and pasta.
